Physical properties
Hardness: 6-7 Mohs; Color: Pink, red, white, and black; Luster: Vitreous to dull; Structure: Granular/Phaneritic; Specific Gravity: 2.63-2.75
Formation & geological history
Formed by the slow cooling and crystallization of silica-rich magma beneath the Earth's surface. This specimen appears water-worn, likely tumbled in a river or glacial deposit.
Uses & applications
Used extensively in architectural construction, countertops, monuments, and as decorative gravel or tumbled stones.
Geological facts
The pink color comes from a high concentration of potassium feldspar (orthoclase). Granite makes up the majority of the Earth's continental crust.
Field identification & locations
Identify by its salt-and-pepper appearance with visible crystals of quartz (clear), feldspar (pink/red), and biotite mica (black). Commonly found in continental mountain ranges.
